But that'd foil any attempt to load (true) Windows DLLs, no?
And I bet most programs ported to Cygwin have to use a mixture of
POSIX and Windows functionality.

Anyway, Cygwin is a mess. MinGW works just fine and is almost
always the better choice. Ok, so I'll take a tested patch, but
only if it doesn't cause any other regressions.
